Hello, I had an unfortunate crash with my fixed wing (Skywalker X5) and ended up frying both my motor and ESC. So I ordered a new motor and ESC from online store. The package arrived today but the problem is they sent the wrong ESC. I ordered a 30A ESC with built in BEC instead they sent a 30A Opto ESC. It will take long time to get the correct ESC from them if I send back the wrong ESC that they delivered to me today. So the question is, can I use the opto ESC with my HKpilot mega 2.7 if i put the JP1 jumper on? Or I still need to add external BEC? I power up my board with HKpilot power module by the way.
